LINEAR TECHNOLOGY
The LTC3805EMSE-5#PBF is a current-mode DC/DC Controller designed to drive an N-channel MOSFET in flyback, boost and SEPIC converter applications. Operating frequency and slope compensation can be programmed by external resistors. Programmable overcurrent sensing protects the converter from overload and short-circuit conditions. Soft-start can be programmed using an external capacitor and the soft-start capacitor also programs an automatic restart feature. It provides ±1.5% output voltage accuracy and consumes only 360μA of quiescent current during normal operation and only 40μA during micropower startup. Using a 9.5V internal shunt regulator, it can be powered from a high VIN through a resistor or it can be powered directly from a low impedance DC voltage from 4.7 to 8.8V. VIN and VOUT Limited only by external components 4.5V Undervoltage lockout threshold Adjustable slope compensation Adjustable overcurrent protection with automatic restart Synchronizable to an external clock ±1.5% Reference accuracy Only 100mV Current sense voltage drop RUN pin with precision threshold and adjustable hysteresis Programmable soft-start with one external capacitor 360µA Low quiescent current Supply Voltage Min: 8.8V Supply Voltage Max: 75V No. of Outputs: No. of Outputs: 1 Output Duty Cycle (%): 95% Controller IC Case Style: MSOP No. of Pins: 10Pins Switching Frequency: 700kHz Topology: Boost, Flyback, SEPIC Operating Temperature Min: -40°C Operating Temperature Max: 85°C Packaging: Cut Tape Product Range: - Automotive Qualifications Standard: - MSL: MSL 1 - Unlimited SVHC: No SVHC (17-Dec-2015) Find similar products grouped by common attribute
